IMPROVEMENT IN BRICK-KILNS.

Specification forming part of Letters Patent No. 202,542, dated April16, 1378; application filed March 3, 1577.

To all whom it may concern Be it known that I, JOSEPH HAAS, of the cityof Delaware, county of Delaware, and State of Ohio, have invented a newand useful Improvement in Brick-Kilns, which improvernent is fully setforth in the following specification and the accompanying drawings, inwhich- Figure l represents the ground plan of the kiln. Fig. 2represents a longitudinal section of the kiln over the lines G H in theground plan. Fig. 3 represents a transverse section of the kiln over theline A B. Fig. 4 represents a transverse sect-ion of the extended orexternal iiues over the line U D. Fig. 5 represents a transverse sectionof the dues over the line E F, showing an end view of the extended orexternal fines. Figs. 6 and 7 represent end views of one of the arches,in which the bricks are placed in a longitudinal and a transversesection.

The object of my invention is to prevent, to a great extent, theoverburning, melting, and spoiling of the bricks in the arches of thekiln. The nature of the invention consists in building the arches byarranging the bricks composing the walls of cach arch alternately in alongitudinalA and a transverse direction, the longitudinally-laid bricksforming a row four deep, whereby a series of three bricks in each row isinterposed between the walls of -the arches in such position that theinner series will be out of contact with the tire, as will behereinafter shown and described.

The drawing shows a kiln with arches constructed according to myinvention, in which it will be seen that each arch a is provided with afurnace, b, and a iiue, c, in a line with said arch, which is built to agreater height than the top of the furnace, and provided with a ii'ue orchimney-hole, p. Externally of the kiln, but between the line offurnaces and the kiln, is a transverse nue-chamber, d, which is theupward as well as lateral extension of the iiues c, and the apertures pare placed in the exterior wall of this iiue chamber, opposite and inline with the tops of the respective arches, and serve to admit airV andregulate the draft, especially in the upper portions of these arches,which are exceptionally high.

K represents the mode of constructing the arch. The bricks are placed inthe arches a in a longitudinal and a transverse direction. Thelongitudinal bricks are laid four deep, in alternate rows with thebricks laid in atransverse direction, said bricks being laid more openthan thelongitudinally-laid bricks, breaking joints therewith to theninth course from the ground, andthe ninth course is laid tight. Fromthe ninth course, and including it, I place the bricks all the same wayto the fourteenth course, which fourteenth course is also laid tight,whereby a series of three bricks in each longitudinal row is interposedbetween the walls ot' the arches in a position out of contact with thetire. By this method of constructing the arches the outer bricks ot' thelongitudinal courses only are exposed to the iiame, while the bricks inthe transverse courses and those above the ninth course have their endsonly exposed to the action of the dame.

I am aware that bricks have been arranged in a brick-kiln transverselyin rows three deep, leaving single intervening' rows of bricks a1'-ranged transversely between said rows.

I am also aware that extended or external lues are not new; but

What I claim, and ldesire to secure by Letters Patent, is-

The method herein described of building the arches of a brick-kiln, byarranging the bricks composing the walls ot' each arch alternately in alongitudinal and a transverse direction, the longitudinally-laid bricksforming a row four deep, whereby a series of three bricks in each row isinterposed between the arches in a position out of contact with thefire, and the bricks in the transverse courses and those above the ninthcourse present their ends only to the action of the llame, substantiallyas specified.
